BackgroundThe factors affecting the outcomes among Indigenous kidney transplant recipients is not fully understood. We conducted a retrospective case control study to identify risk factors beyond those explained by the ANZDATA registry.AimTo identify the risk factors for loss of kidney transplant function or death among Indigenous kidney transplant recipients.MethodsCases were defined as all Indigenous Australian kidney transplant recipients from 1 January 2005 to 31 December 2015 from the major hospitals in the Northern Territory (NT) and South Australia (SA) who experienced graft loss (including patient death) up to 2-years post-transplant. Controls (matched 4:1) were defined as all indigenous kidney transplant recipients during the same period with functioning transplants at 2-years post-transplant operation. Matching was done on gender and diabetes status. Regression analysis adjusted for age was used for comparing cases and controls.ResultsThere were 17 cases and 68 matched controls. Among cases, the odds ratio for more than one hospital admission episode (compared with ≤1 episode) in the 2-year pretransplant period was 6.2 (95% confidence interval, 1.2-32.5). However, there were no significant differences in the frequency of comorbidities at renal replacement therapy start, cardiovascular intervention pretransplant, pretransplant infection screening, age and gender of the donors, frequency of admission episodes where an infection was documented, the total length of inpatient stay or admission to intensive care unit during pretransplant hospital admission between cases and controls.ConclusionEarly graft loss was associated with a higher frequency of hospital admissions in the 2-years pretransplant period. In contrast, other measured factors in the pretransplant period did not predict these adverse outcomes.© 2021 Royal Australasian College of Physicians.
